首先在Converse3D三维场景编辑器下按照教程制作一个导航图，并使用动态导出保存为.c3d文件。此外，在程序中的实现方法：

BOOL CXXView::PreTranslateMessage(MSG* pMsg)
{
if (pMsg->message==WM_LBUTTONDBLCLK)

{
  CRect clientRect,daoHangRect,gd1_rect,gd2_rect,gd3_rect,gd4_rect;
        GetClientRect(clientRect);

  daoHangRect.left=0;
  daoHangRect.top=0;
  daoHangRect.bottom=clientRect.Height()*0.1; //在编辑器中设置的导航图的大小应与此处一致
  daoHangRect.right=clientRect.Width()*0.2;

  gd1_rect.left=daoHangRect.Width()*0.1;      //在编辑器中设置的热区大小应与此处一致
  gd1_rect.right=daoHangRect.Width()*0.15;
  gd1_rect.top=daoHangRect.Height()*0.85;
  gd1_rect.bottom=daoHangRect.Height()*0.95;

  gd2_rect.left=daoHangRect.Width()*0.2;
  gd2_rect.right=daoHangRect.Width()*0.25;
  gd2_rect.top=daoHangRect.Height()*0.85;
  gd2_rect.bottom=daoHangRect.Height()*0.95;

  gd3_rect.left=daoHangRect.Width()*0.3;
  gd3_rect.right=daoHangRect.Width()*0.35;
  gd3_rect.top=daoHangRect.Height()*0.85;
  gd3_rect.bottom=daoHangRect.Height()*0.95;

  gd4_rect.left=daoHangRect.Width()*0.4;
  gd4_rect.right=daoHangRect.Width()*0.45;
  gd4_rect.top=daoHangRect.Height()*0.85;
  gd4_rect.bottom=daoHangRect.Height()*0.95;

     ScreenToClient(&pMsg->pt);
      if (daoHangRect.PtInRect(pMsg->pt))
   {

        if (gd1_rect.PtInRect(pMsg->pt))
        {
   m_conver3D.SearchObject("模型1");
        }
        else if (gd2_rect.PtInRect(pMsg->pt))
        {
   m_conver3D.SearchObject("模型2");
        }
   else if (gd3_rect.PtInRect(pMsg->pt))
        {
   m_conver3D.SearchObject("模型3");
        }
        else if (gd4_rect.PtInRect(pMsg->pt))
        {
   m_conver3D.SearchObject("模型4");
        }
}

return CFormView::PreTranslateMessage(pMsg);
}
